An extraordinary, highly cohesive geologists’ or systematic prospector's reference collection compiled during the early-to-mid 20th century. This lot represents an irreplaceable snapshot of classic, closed, and entirely exhausted mining localities across the United States and classic global districts.The supreme value of this lot lies in its unbroken provenance. Every specimen is paired with its original field label—ranging from fountain-pen ledger fragments to typed notations—detailing extinct mines, specific geographical horizons, old chemical formulas, and historical mining terminology.Significant Highlights Within the Lot
